| 摘 要： | 【目的】 研究扁桃棉花间作对棉田主要害虫及其主要捕食性天敌的影响,为扁桃棉花间作模式下棉田害虫防治和天敌的保护利用提供理论依据。【方法】 采用目测法,调查2种扁桃棉花间作棉田和单作棉田棉花的主要害虫及捕食性天敌的种群数量。【结果】 扁桃棉花间作(南北向)有利于棉田蚜虫和捕食性天敌的发生,扁桃棉花间作(东西向)则不利于其发生。扁桃棉花间作不利于棉田牧草盲蝽的发生;扁桃棉花间作对棉田棉蓟马和棉铃虫的发生无影响;不同类型棉田烟粉虱的发生与虫源地距离有关。扁桃棉花间作有利于棉田蜘蛛的发生。【结论】 扁桃棉花间作对棉田主要害虫及捕食性天敌存在一定的影响。

| Abstract: | 【Objective】 To explore the effects to main pests and predatory natural enemies on cotton under almond-cotton interplanting patterns. Provide theoretical basis for pest control and natural enemy protection and utilization in cotton fields.【Method】 Populations of main pests and predatory natural enemies in two types of almond-cotton intercropping and pure cotton field were investigated by visual method.【Result】 Almond-cotton interplanting (south-north) patterns are beneficial to occurrence of aphids and predatory natural enemies in cotton fields, but almond-cotton interplanting (east-west) to the disadvantage of those. Two types Almond-cotton interplanting patterns are beneficial to occurrence of Lygus pratensisand have no effect to Thrips flavus and Helicoverpa armigera. The occurrence of Bemisia tabaci is related to the distance from the source. Almond-cotton interplanting are conducive to the occurrence of spiders in cotton fields.【Conclusion】 Almond-cotton intercropping has certain effects of main pests and predatory natural enemies in cotton fields, it depends on the direction of trees. |
